Trilogy Metals Provides Update on President Trump’s Executive Orders and Actions by Department of Interior Aimed at Advancing the Ambler Access Project in Alaska March 25, 2025 March 25, 2025 – Vancouver, British Columbia – Trilogy Metals Inc. (TSX / NYSE American: TMQ) (“Trilogy Metals”, “Trilogy” or “the Company”) is providing an update on the Ambler Access Project (the “Ambler Road”) - the proposed 211-mile, industrial-use-only road from the Upper Kobuk Mineral Projects to the Dalton Highway that would enable the advancement of exploration and development at the Ambler Mining District in Northwest Alaska, home to some of the world's richest known copper-dominant polymetallic deposits. On January 20, 2025, President Trump signed a comprehensive executive order titled “Unleashing Alaska’s Extraordinary Resource Potential”, instructing agency heads across the federal government to revoke, rescind or revise regulations that are inconsistent with resource development in Alaska, including those issued by former President Joe Biden when he was in office. It places a moratorium on all activities related to the rejection of a right-of-way permit to build the Ambler Road and directs the reinstatement of the prior Trump Administration’s 2020 approval of the right-of-way permit to build the Ambler Road. The order was broadly welcomed by Alaska’s political leaders, including Senators Dan Sullivan and Lisa Murkowski, and Representative Nick Begich. Department of Interior Secretary Doug Burgum subsequently signed a series of secretarial orders, echoing the executive orders signed by President Trump. Secretary Burgum’s Order 3422 on February 3, 2025, also titled “Unleashing Alaska's Extraordinary Resource Potential”, directs the submission of an action plan to him that includes “steps to expedite the permitting and leasing of energy and natural resource projects in Alaska (including the rights-of-way and easements for roads that enable this development to occur).” On March 20, 2025, President Trump signed an executive order titled “Immediate Measures to Increase American Mineral Production”, which underscores the importance of securing a stable and predictable domestic supply of critical minerals (including copper and gold) that are essential for the nation’s defense, technology, and infrastructure, and to reduce the reliance on foreign imports. The order directs federal agencies to expedite approvals for mineral production projects. Also on March 20, 2025, Secretary Burgum announced that the Bureau of Land Management will work towards partial revocation of public land withdrawals to convey these lands to the State of Alaska. This action is expected to help advance the Ambler Road. Secretary Burgum’s announcement was commended by Alaska Senators Sullivan and Murkowski, and Representative Begich in a joint statement on March 20, 2025. Tony Giardini, President and Chief Executive Officer of Trilogy Metals, commented, “Recent actions taken by President Donald Trump and Interior Secretary Doug Burgum signal a positive path forward for the Ambler Road. This transportation corridor is crucial not only for providing access to the minerals that are vital to U.S. national security and prosperity, but also for much-needed economic growth and job creation in Alaska. Trilogy Metals is committed to working with all stakeholders on progressing the road, to unlock the vast natural resource potential of the Ambler Mining District.” Resolution in Support of the Ambler Road has been Passed by Alaskan Tribal Council On March 11, 2025, the Kobuk Tribal Council, on behalf of the community of Kobuk – one of the communities located close to the proposed Ambler Road, passed a resolution in support of the road. The tribal council acknowledges that the road could provide local jobs and economic benefits to the community while safeguarding a traditional subsistence lifestyle. “We have been studying this project since it was announced. The conversations about subsistence, the cost of living, and jobs for our youth are important to us as we look to the future of the region as Red Dog winds down and our people need work to remain in our villages,” said Henry Horner Sr., President of the Kobuk Tribal Council, in the March 21, 2025 announcement of the resolution by the Alaska Industrial Development and Export Authority (“AIDEA”).
